 :O  Even at half resolution, it's the most artistic and realistic of all. 
Light is almost perfect for me.

Looks good from what you can see at that size.  I think you should try to
render it in full size with slightly weaker radiosity settings if
necessary.

Oh, wow... This is definitely the best so far.

Looking good.. what was the trace time? The quality suggests that a full
size might take ages. See you made the same mistake with the SunPos as I
did. The scene looks better that way but:

// Lstm:  Meridian of your local timezone (+1 hour =  +15 deg)
//        in degrees (east = positive, west = negative)

so I guess Lstm should be +15 not +1. Hope you haven't started a new trace
yet. Somehow after 13,5h I don't want to re-start anymore.

That's impressive.  The light quality is, by far, the best I have
seen amongst every other rendering of that church (including
lightscape, mental ray, etc...).

I hope the final rendering will do justice to it.

I hope that this dynamic range stuff will be implemented in POV-Ray
someday.

Certainly the best so far... It certainly helps a lot knowing about lighting
like you do. I'm wondering about the light position, though, as the sun
seems lower in your image than in the other ones. I've been using these
parameters :
//    SunPos(Year, Month, Day, Hour, Minute, Lstm, LAT, LONG)
    SunPos(2001, 6, 1, 14, 0, 15, 45.44, 15.53)

How much memory is required, BTW ? Is it possible to render it in chunks, as
this can reduce greatly the necessary memory ?

  I suppose that it would take about 10-20 lines of code to implement it
(plus the code needed for a new keyword in global_settings...). And perhaps
not even that much.

Still not the same position as in other entrys or I have
the axes mixed up. I'm just going to leave it as it is.
This time I use the original sandstone maps because in
some reference images the color is less saturated.

Will we be seeing a patch by you for the next MegaPOV? :)

  Why the light source location in my original code wasn't good? I set it
with the instructions given in the site.
